I would like to pick some technically minded minds on a gearbox query. I have a 2012 bravo multiair with a six speed gearbox. For the longest time i have been assuming this to be GMs dreaded "cheese box" and have been planning a gearbox oil change for a while in a vain attempt to try at least to prolong the inevitable rebuild for as long as possible. So last weekend I bought the oil, did a bit of research as to where the filler point was and stone me the filling point on my box is in a different place in fact the whole box looks different with the filling point on top of the diff casing.

Here's a photo of an M32 box taken from the Internet. The filling point can be see as an allen bolt by the gearbox mount.



And this is the closest box I can find that looks like mine taken from a 500x



Is this in essence an M32 with a different casing?

To me, from the one picture of your gearbox it looks to be the M32.
You might be lucky and have the newer design end case that doesn't have the level plug, and has additional oil galleries and i think bigger bearings... but looks to be an M32.
